Hey!
Can you check the cockpit service from host
systemctl status cockpit
In case it is not started
systemctl start cockpit

This issue could be because of a firewall exception.
You can try this -
firewall-cmd --permanent --add-port=9090/tcp
firewall-cmd --permanent --add-port=9090/udp
systemctl restart firewalld

If the problem still persists, you should check for 
systemctl status cups-browsed
In case it is not started, try starting the service

“Unexpected error - Cockpit had an unexpected internal error.”

 

“You can try restarting Cockpit by pressing refresh in your browser. The javascript console contains details about this error (Ctrl-Shift-J in most browsers).”

index.js:15 Refused to apply inline style because it violates the following Content Security Policy directive: "default-src 'self' https://XYZ.co.za:9090". Either the 'unsafe-inline' keyword, a hash ('sha256-47DEQpj8HBSa+/TImW+5JCeuQeRkm5NMpJWZG3hSuFU='), or a nonce ('nonce-...') is required to enable inline execution. Note also that 'style-src' was not explicitly set, so 'default-src' is used as a fallback.
